It all depends on the quality of information that the poster wants.
As Shivan said above, there is already a wealth of information on the forum, if one is inclined to look for it, by those that have opinions that others frequently pay for. That information is here for anyone that bothers to look for it, for free. That does not mean that there is no new information, or that a single post is the be-all, end-all of the topic, but it gives the reader a depth of knowledge that will permit the more informed discussion of a topic, discussion at a level that most of us are accustomed to and direct our comments to.
There are numerous topics that have been beaten to death, and lacking any advancement in those topics, there isn't going to be any progress in the topic other than what was already stated (usually to a better/more concise end by our highly knowledgeable user base).
What discussion would you rather participate in, and what would provide a better resource for those looking for information:
1- I just bought my first AR. It's an XXX. Is it any good? I paid $XXXX for it. How do I clean the barrel? I heard that I need to break the barrel in, how do I do that? I've been shooting it dry except for a few drops of WD40. I want to shoot at 1,000 yards, is there ammo cheaper than M855 that would be as good at that range? I've been using a Barska 3x optic, it sure is great at 25 yards, but how high will I have to aim at 1,000?
2- I'm looking for precision ammo for 600 meter iron sight shooting. I've done a search, and found ammo brands X, Y, and Z. X is cheaper than Y and Z, but does it work as well at that distance out of a 16" barrel with 1inWhatever twist?
Has anyone compared the 3 options in such a barrel?
Now litter option 1 with gross grammatical errors, irrelevant punctuation, and "lolz", and what one will get attention by those worth listening to?
A quick search would answer everything from the first example, and is pretty much guaranteed to raise the ire of our primary member base. There are plenty of sites to go to where one can argue the merits of "good as" firearms and gear, get 300 responses about how to color in your roll marks, or be spoon-fed basic information, but that really isn't the intent of this site.
New members are most certainly welcome to join and participate, but if the entirety of your firearms knowledge and training comes from gun magazines, family members, and the local gunshop employee, you might want to take the time to read and get a feel of the site before jumping into a conversation.
Having a resource like M4, where thousands of members can discuss and share information, and have it all easily found, is incredibly valuable. It is what this site is best at, and is how we want to keep it. I say that not only as a moderator and industry professional, but also as a member that cares about the forum and the community.
